A SEAL-PRESS.

SPECIFICATIONforming part of Letters Patent No. 779,023, dated January 3, 1905.

Application led April 13, 1904. Serial No. 202,964.

To all whom, it may concer-71,:

Be it known that I, FRANKLIN W. BROOKS, a citizen of the United States, residing at Washington city, in the District of Columbia, have invented certain new and useful Improvements in Seal-Presses; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in seal-press, and has for its object the production of a press especially adapted for compressing seals, such as shown and described in Letters Patent No. 654,940, granted to me July 31, 1900. The seal shown and describedin this patent is of elliptical vdesign and after the ends of the cord have been passed through threading-holes at one end and through a slot in the opposite end they are crossed to form a single knot, and the latter is then drawn within the slotted end of theseal and up against the bridge of metal between the two threading-holes and the seal is then compressed to lock the cord and knot in place and to impress any desired characters upon the outer surface of the seal.

My present invention has for its object the production of a press and dies which ,will cause the desired characters to be impressed upon the faces of the seal and which shall also form a bridge of metal behind the knot formed in the cord and to securely hold the same between such bridge and the bridge existing between the threading-holes. l

VVth these ends inview my invention consists in the details of construction hereinmerals to the accompanying drawings, inV

which.-

Figure 1 is a side elevation of a press embodying my invention. Fig. 2 is a section through the jaws and dies, taken on the line a e of Fig 1. Fig. 3 is a detail section taken on the line b of Fig. 1. Fig. 4 is a front or end r before compression of the latter.

view of the jaws and dies and showing a removable stop for properly locating the seal to be subjected to the compressive action of the press. Fig. 5 is a perspective view of the two dies. Fig. 6 is a plan view of a seal such as shown in the patent referred to and before the loop or knot in the cord has been drawn into the seal. Fig. 7 is ahorizontal section of a seal and showing the location of the knot after it has been drawn within the seal and Fig. 8 is a similar view after the seal has been, subjected to compression by my improved press, and Fig. 9 is a central longitudinal section taken on the line c c of Fig. 6 before the seal has been compressed.

Similar reference-numerals indicate like parts in the several figures of the drawings.

1 represents the handles, and 2 the jaws, of an ordinary toggle-lever press. The jaws are each formed with a screw-threaded channel 3 to respectively receive a male die 4 and a female die 5, each of which is formed with a screw-threaded shank 6. The shank of the female die is formed with an axial screwthreaded channel adapted to receive a screw 7, which holds the same in fixed relation with the jaw of the press, and the Vmale die is held in any desired adjusted position by an anvilscrew 8, all as clearly shown at Fig. 2. The male die is formed with a central cone-shaped projection or nipple 9, and the female die is formed with a central corresponding recess or countersinklO, as clearly shown at Fig. 5.

11 is a gage or stop for properly adjusting the seal to be compressed between'the dies and is formed with a'screw-threaded shank by which it is secured to one of the jaws, as clearly shown at Fig. 3.

The faces of the dies are provided in the usual way with any characters which it may be desired to impress upon the seal. In assembling the several parts of niy improved press the handles and jaws are pivotally connected in the ordinary manner and with the jaws in open relation. The gage or stop 11 is screwed into its seat and properly adjusted. The dies 4 and 5 are then screwed into their seats in the respective jaws, and the female die is locked in fixed position by the screw 7,

IOO

and the male die is held in its adjusted position by the anvil-screw 8.

In using the press thus constituted for the purpose of compressing seals of the character described the seal is introduced between the dies until its edge abuts and is arrested by the gage or stop l1. approach by closing the handles'l, and as the dies approach the projection or nipple 9 first produces the central bridge from the side of the metal adjacent to the nipple, and the continued approach of the dies carries this bridge across the interior space in the seal and into the metal of the opposite side and forces a corresponding amount thereof into the recess or countersink of the female'die, while at the saine time the characters are impressed upon the faces of the seal. As this bridge is being thus formed it tightly locks the knot or loop in the cord between it and the metal bridge between the threading-holes of the seal, as clearly illustrated in the figures of the drawing showing the seal.

What I claim as new, and desire to secure by Letters Patent, is-

l. A seal-press embodying in its organizarlhe dies are then caused to tion a pair of operating-handles and two Vibrating jaws, a die having a shank threaded into one.of the jaws and retained in fixed relation therewith by a screw axially threaded in the shank of the die, and having in its eX- posed face a central recess or countersink and a die having its'shank threaded in the other jaw and adjustably held by an axially-arranged anvil -screw, and having its face formed with a central projection or nipple, substantially as and for the purpose set forth.

2. In a seal-press such as described, in combination with dies secured within the jaws thereof, a gage or stop for properly lo` cating a seal, said gage or stop formed with a screw-threaded shank and secured thereby to one of the jaws, substantially as hereinbefore set forth.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

FRANKLIN W. BROOKS.
